PRESSER-FOOT AND WELT- GUIDE COMBINED.

SPECIFICATION forming part of Letters Patent No. 366,259, dated July 12,1887.

Application filed March 4, 1886. Serial No. 193,954. (No model.)

To aZZ whom, it may concern:

Be it known that I, ELBRIDGE 0. Ross, a citizen of the UnitedStates,residing at Stou ghton, in the county of Norfolk and State ofMassachusetts, have invented certain new and useful Improvements inPresser-Foot and WVelt- Guide Combined; and I do hereby declare that thesame are fully described in the following specification and illustratedin the accompa- 1o nying drawings.

This invention relates to improvements in pressenfoot and welt-guidecombined, for the purpose of guiding a welt onto the bottom of a lastedshoe-upper while it is in the act of I 5 being sewed to the upper andinsole of a boot or shoe, as will hereinafter be more fully shown anddescribed, reference being had to the ac companying drawings, where-Figure 1 represents a front view of the device, showingit in'positionrelative to neighboring parts of a McKay wax-thread sewing machine. Fig.2 represents a plan view of the device, and Fig. 3 represents a bottomview of it. Fig. 4 represents a side view of the device as seen from Xin Fig. 1; and Fig. 5 represents a longitudinal section on the line A B,shown in Fig. 4.

Similar letters refer to similar parts wherever they occur on thedifferent parts of the drawings.

In Fig. 1, a is the bottom plate of the head of an ordinary McKaywax-thread sewing-machine, on which I) is the needle-bar; b, the hookedneedle; 0, the castoff point; d, the feedpoint; d, the feed-point block;4, the tongue for the feed-block; e, the link for operating thefeed-point, and f the stirrup, with its spring f, for drawing back thefeed-point in the usual manner. 9 is the work supporting horn, as

0 usual, and It represents the presser-i'oot block secured in anadjustable manner by means of setscrew z to the vertically-adjustablepressure-foot rodk, as is common on McKay wax= thread sewing machines.

5 front grooved cam-plate secured to the presserfoot block h in theordinary way.

Such parts as above described are well known in the art of wax-threadsewing-machines and form no part of my present invention, and are merelyrepresented in the drawings to show .the welt that is used.

d represents the.

the class of sewing-machines to which my in vention relates.

To the lower end of the presser-foot block h is secured, by means of aset-screw, h, the shank l of the presserfoot Z, having on one side aninterior groove, Z, and opposite to the latter the adjustable guideplatein, having an inwardlyprojeeting lip, m, as shown in Fig. 4:, such platebeing adjustably secured to thepresser-foot Z by means of set-screws mm, passing throughslot-holes Z Z in the presserfoot Z and screwed intoperforations in the guide-plate m, as shown. The groove Z and theguide-plate m, with its lip m, serve to receive the welt L and to guideit properly to the needle as it is being fed forward by the feed-point(1 during the operation of sewing the welt, upper or, and insole 0together, as

represented in Fig. 4-.

Z is a slotted cut-away portion in the presserfoot Z, to enable thefeed-point d to move freely backward previous to feeding the welt Lforward without interfering or coming in contact with said presser-footZ.

The guide-plate m is made adjustable to and from the groove Z, accordingto the width of Z is a lip on the under side of the presser-foot Z, suchlip forming the under side of the welt-receivinggroove Z, as shown inFig. 4:.

In sewing the welt to the shoe-upper n and insole 0 it is essential thatthere should be arranged on the presser-foot device an adj ustable upperguide, so as to properly guide the boot or shoe relative to the welt asit is being sewed, and for this purpose I locate below the plate at theupper guide 19, having a rearwardly-projecting bar, 1), that is pivotedto the under side of the presser-foot block h by means of a screw orpin, 19', passing through a perforation in the rear end of the bar pandscrewed or otherwise secured to the presser-foot block h, as shown inFigs. 3 and 5. It is also essential that the upper-guide 19 should becapable of a lateral adjustment to and from the outer edge of the upperit during the operation of sewing the welt, owing to the peculiarcurvatures at the shank portion as compared with other portions of theboot or shoe, and during such operation the welt must be guided nearerto the middle of the shoe at the shank part and farther out at the otherparts of the shoe. ,Such adjustment in practice is about one-eighth ofan inch, or a little more or less, according to the size or shape of theshoe. For this purpose I provide the bar 1) with an extension, phavingaslot-hole, 1), made through it, in which is located the eccentriccam or sleeve q, that is pivoted to the presserfoot block it by means ofa pin or screw, q, passing through the eccentric cam or sleeve q andsecured to the block h, as shown in Fig. 5. 'In one piece with theeccentric cam'or sleeve q is made a projection or handle, q, for theoperator to take hold of or otherwise manipulate when he desires tochange the position of the upper-guide 1) relative to the welt L.

Having thus fully described the nature, con-- struction, and operationof my invention, I wish to secure by Letters Patent, and claim- 1. Thepresser-foot Z, adjustably secured to block h, and having a groove torecelve the welt, combined with an upperguide, 19, arranged below thewelt-guide, as and for the purpose set forth.

2. The block 71, having pivoted to it the upper-guidep, in combinationwith the slotted extension 1) the cam or eccentric q, pivoted at q, andprovided with the handle or projec- Witnesses:
